Game of Thrones star Maisie Williams says she had to wear a strap across her chest to reverse puberty while filming the fantasy series. The actress, 22, has played Arya Stark in the series since she was 11 and explained that growing up on the HBO series has come with its own challenges, reports dailymail.co.uk.

The star told the US show "60 Minutes" that when she hit puberty she had to wear an uncomfortable strap to keep her chest flat whilst her character was "pretending to be a boy".
